2. Gigabit Ethernet: Progress Summary Completed Tasks  Received Parts  Built first board  Began testing on first board  First Draft of Report  New Website  Spring Break Fun Next Week’s Tasks  Troubleshoot first board  Build, test, and troubleshoot second and third board designs  Design review for next fabrication  Order additional parts

3. Gantt Chart

4. Board Construction  Boards and all of the parts arrived either before or over Spring Break  Construction began upon arrival from Spring Break  First complete board finished Tuesday afternoon

5. Board Construction (cont)  Each board has three Tx and Rx circuits One common anode (AOC VCSEL) One common cathode (Emcore VCSEL) One aggressive design  First circuit constructed and tested was common anode

6. Board Layout Review

7. Board Construction (cont)  0603 parts are tiny…was it a good idea?  Found a mistake on the board and used board surgery to attempt to fix it

8. Board Testing  Rx component works  Tx has problems Board surgery did not work well enough There is a short somewhere on the board that we need to find
